JAMES K. DIAMOND, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO CLIPPER BE'L'I LACER COMPANY, DIE GRAND RAPIDS, MICHIGAN.

MACHINE FOR SETTING BELT-FASTENERS.

To all whom it may concern Be it known that 1, JAMES K. DIAMOND, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Machines for Setting Belt-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. appertains to make and use the same.

My invention relates to improvements in machines for setting belt fasteners and more particularly to the style of machine shown in my Patent #1,012,614 issued December 26th, 1911, and adapted to set the style of belt fasteners illustrated in the drawings.

The object of my present invention is to provide improved holding means for the fasteners when inserted in the machine, whereby the device is adapted to properly operate in connection with fasteners of dif ferent sizes and belts of various thickness.

The invention consists essentially of holding means provided with means whereby the retaining rod is freely movable toward and away from the plane of the anvil and thus permits of the use of fasteners of various gage of wire and also permits the bending of such fasteners substantially uniform at each side of the said rod, thus maintaining the loop of the fasteners midway between the planes of the opposite sides of the belt regardless of any variation in thickness of the belt, and in various features of construction and arrangement as hereinafter more fully described and particularly pointed out in the claims, references being had to the accompanying drawings, in which:

Figure 1 is a vertical section of a portion of a machine of the kind referred to having my present invention applied thereto. Fig. 2 is a plan view of a portion of the same with parts broken away to show the construction, and Fig. 3 a detail in end elevation of a portion of the holding mechanism.

Like numbers refer to like parts in all of the figures.

1 represents the anvil on which the fasteners are supported. 2 a clenching bar to engage the fasteners opposite the anvil and clench the same into the belt.

3 is a bed plate attached to the anvil and Specification of Letters Patent.

Application filed December 21, 1912.

Patented Apr. 21, 1914. Serial No. 738,063.

projecting from beneath the same under the loop of the fasteners. Laterally slidable on this bed plate 3 toward and away from the anvil is a bar 4: having shallow grooves 4 in the side adapted to engage the crowns of the fasteners. A sheet metal housing 6 incloses the bar and extending through openings in the rear of the housing are spring pressed plungers 5 to slide the bar toward the fasteners and yieldably hold the same in proper position while being clenched. Obviously for machines of moderate size one plunger is sufficient and will operate quite as well as more. The housing 6 projects upward beyond the plane of the anvil for a suitable distance and the side of the housing next to the rear edge of the anvil and extending upward from the same is substantially at right angles to the surface of the anvil and is provided with slots 7 spaced apart at regular intervals to receive the crowns or loops of the respective fasteners. To retain the crowns of the fasteners within the housing a longitudinally removable pin 8 extends through the housing and fasteners close to the slotted side of the housing and is freely movable toward and away from the plane of the anvil. The ends of the housing are also provided with slots 9 there in parallel withthe slotted side of the housing'whereby the rod 8 is free to adjust laterally in a direction substantially at right angles to the surface of the anvil. It is thus automatically adjusted to fasteners having crowns of differing radii and will also fit fasteners of different gages of wlre. It also is free to move upward as the fasteners are clenched thus permitting the wire to bend equally at opposite sides thereof. By this lateral movability of the rod it is thus automatically adjusted to both variations in shape and gages of wire in the fasteners and also to various thicknesses of belts and when the fasteners are clenched the axis of the crown of the fasteners will be accurately midway between the planes of the opposite surfaces of the belt, regardless of the thickness thereof.

When the machine is operated to clench the fasteners, the bar 4 is yieldably slid by the plunger 5 against the crowns of the fasteners and thus clamps the same between the rod 8 and the bar with each crown in a respective shallow groove of the bar and also clamps the rod 8 between the slotted side of the housing and the inner or concave portion of the crowns of the fasteners, whereby the fasteners are all held in proper parallel alinement and each vertical to the aXis of the rod 8.

By the improved construction shown I have adapted the machine to operate with entire satisfaction and accurately in conjunction with a variety of sizes of fasteners and a variety of thicknesses of belt, not possible in my prior form of machine.

What I claim is 1. In a machine for setting belt fasteners, a holder comprising an anvil, a housing having slots at intervals to receive the fasteners, a pin to retain the fasteners in the housing movable toward and away from the plane of the anvil, and a movable bar in the housing slidable toward and away from the pin to engage the fasteners oppositely to the pin.

2. In a machine for setting belt fasteners, a holder comprising an anvil, a housing having one side substantially perpendicular to the anvil and provided with a series of slots to receive the fasteners, a pin extending through the housing and laterally movable therein toward and away from the plane of the anvil, a bar laterally slidable in the housing, and means for sliding the bar toward said pin.

3. In a machine for'setting belt fasteners, a holder comprising an anvil to support the fasteners, a clenching bar above the anvil to engage the fasteners, a slotted member extending upward substantially at right angles to the surface of the anvil, a bar slidable toward and away from the slotted member, a pin between the said member and bar and freely movable toward and away from the plane of the anvil, and means for yieldably moving the bar toward said member.

4. A machine for setting belt fasteners, comprising an anvil, a clenching bar above the anvil and movable toward and away from the same, a housing having a slotted side at the rear of the anvil, a pin laterally movable in the housing on the inner surface of the said slotted side, a bar slidable in the housing toward and away from said side and a springpressed plunger engaging the bar and operated by movement of the clenching bar.

5. In a machine for setting belt fasteners, an anvil, a clenching bar above the anvil, a housing at the rear of the anvil and projecting above the plane thereof, and also having a series of vertical slots in the side next the anvil and slots in the ends, a pin extending through the housing and movable toward and away from the plane of the anvil in said end slots, a bar slidable in the housing toward and away from the slotted side thereof and provided with shallow grooves opposite the said slots, and a spring pressed plunger engaging the bar.

In testimony whereof I aflix my signature in presence of two witnesses.
